SILO.

Application filed March 15, 1924, Serial No. 699,564. Renewed .Tune 15,1925.

To all whom t may concern:

Be it known that I, CLARENCE I-IoAnD, a citizen of the United States ofAmerica, residing at Victoria, in the county of Victoria, BritishColumbia, Canada, have invented certain new `and useful Improvements inSilos, of which the following is a specification.

My present invention relates to silos and similar wooden buildingstructures for storing yensilage grain and various other things, but itis especially directed to the construction of a silo or storage bin madeup of short lengths of lumber or timber for the purpose of reducing thecost of construction and enhancing the etciency of the silo.

In the erection and construction of the silo according to my invention Iutilize short lengths of lumber or timber which are usually treated aswaste material in the mills, and thus not only prevent waste ofmaterial, but also reduce the cost of erection of the silo. l

According to my invention the material to be used in the silo can be cutto standard sizes and properly fashioned at the mill, for futureassembly and erection on the farm or at other desirable places, withoutthe necessity for employing skilled labor.

A strong self-sustained structure of polygonal shape is built up fromthe prepared material, and while the number of sides of the silo may bevaried I have found it desirable to construct the silo with eight sidesas herein illustrated.

The invention contemplates the use of complementary, intersectingtimbers arranged in courses which courses are made up of pairs ofstandard length and fashioned or cut with interlocking joints at theirrespective ends. The joints are arranged in such manner as to divert themovement of air currents therethrough and by thus preventing directpassage of air through the joint increase the distance of air travelthrough the wall of the silo and therefore the structure is renderedmore air tight, while the natural expansion of the timbers iscompensated .for and utilized for the purpose of tightening the jointsof the wall structure.

In the accompanying drawings I have illustrated one ccniplete example ofthe pliysical embodiment of my invention wherein the parts are combinedand arranged in accordance With thebest mode I have thus far Figure 4 isa horizontal sectional view at 70 line 4L-4 of Figure 2.

Figure 5 is a perspective View of one of the timbers and Figure 6 is aperspective view of a complementary timber which timbers are joined inpairs in a horizontal course.

Figures 7 and 8 are perspective views of a complementary pair of timbersslightly modified in their joint structures.

For convenience of illustration I have indicated in Figure l aconventional form of base or circular foundation as 1 which may be ofconcrete or similar material, or any other desirable form of base orfoundation may be utilized to support the silo erected thereon.

In the forni of the invention herein shown a structure of eight sides isillustrated, and in one of tliese sides a conventional form of door isshown comprising hinged sections 2 and 3 with a hinge 4 and retainedWitliintlie door frame 5 in any suitable manner to give necessary accessto the interior of the silo.

The timbers 6 and 7 are used in pairs to form horizontal courses, andeach of these intersecting timbers is fashioned with a tongue 8 andcomplementary groove 9 in order that the courses may be locked togetherand a sealed joint be formed between the courses.

For interlocking the intersecting timbers they are cut out near theirrespective ends, as best illustrated in Figures 5 and 6, where thetimber 6 is shown with two vertical grooves '10 and 11 of a widthsuiiicient to receive the thickness of the complementary timber. Thesegrooves have their walls on `angular lines, in this instance at an angleof forty five degrees, and tlie Walls of the spaced grooves are onconverging lines rl`he grooves e-Xtend vertically from top edge tobottom edge ot the timber and are out in the inner tace thereof. Thetimber is also fashioned with transverse notches as 12 and 13 less thanthe Yfull thickness of the complementary timber and the notches ei;-tend downwardly Jfrom the upper or tongue edge ot the timber to formtenons 14 and 15 at the lower or grooved edge of the timber.

The timber 7 is tashionedjwith complementary vertical grooves 16 and 17on its inner tace ot a ,vidth to receive the full thickness et acomplementary timber and the walls of these grooves are disposed atangles of vforty tive degrees and on converging lines.

Upwardly extending notches 18 and 19 are cut across the lower edge ofthe timber 'l' to form, together with the grooves 16 and 17, tenons Q0and 21,.

lt `will be apparent, at'ter the timbers 6 have been placed Ain spacedrelationship, that the four complementaryv timbers 7 are slipped overthem with the notches 18 and 19 and grooves 16 andi? litt-ing over thecomplementary cut away parts ot the tour timbers 6,*the tenons ot therespective timbers being `brought together, and rthe upper and lower'faces or edges .of the tim bers forming a flush and continuous edgearound the silo as indicated in the drawings.

This close association of the parts of the intersecting timbers at theirjoints eliminates the possibility of direct. travel oi air through thesilo wall at the joints and affords practically air tight joint which isbraced against relative movement ot the timbers and the joint isarranged in such manner that any lateral swelling will result intightening the jointand render the wall more durable and er'licient.

In Figures 7 and 8 the pair ot timbers are both c ut away or notched onboth their upper and lower edges,4 and grooved on their inner facessimilar tothe pair ot timbers in Figures 5 and '6, for the purpose ofpermitting the timbers to be interlocked iu staggered formation.

rlhus the timber 22 is fashioned near each end atits innerI side with avertical groove 23 and upper and lower notches 2st and 25 respectivelyto form the notch 26.

'lhe complementary timber' 27 is also 'fashioned with spaced verticalgrooves Q8 of a width to receive the thickness ot a complementarytimber, and this timber 2'? is fashioned with upper and lower notches.29 and 30 respectively to torni the tenon 31 in connection with thegroove 28. The walls ot' the spaced grooves and notches are alsodisposed at angles and on converging lines.

ln assembling the course during the erection et the silo the right endot timber is slipped over the lettend of the complementary timber 2T tointerlock grooved and notched portions.

When the number ot' timbers in a coursel is varied to increase ordiminish the numher of sides to the silo, the angles at which the wallsot the grooves and notchesare dis-- posed are oi' course changed toconform to the angular disposition of the intersecting timbers.

Having thus fully described my inven tion, what l claim as new anddesire to secure by Letters Patent is:

1. ln a silo, a series of intersecting tim bers forming a horizontalcourse7 each et' said timbers having a pair ot spaced vertical groovesat it-s inner side having Atheir walls disposed on converging lines andtransversely extending notches at one edge of said timber merging withsaid grooves to form tenons.

Q. n silo timber having spaced vertical grooves therein with their wallson converg ing lines, and upper and lower notches in said timber mergingwith said Vgrooves Vto term tenons in the timber. n

in testimony whereof I have aiiiXed my signature.

CLARENCE HOARD.
